Red face Holley flooding

This is probally a dumb, easy question so here you
go. I've got a 4160 Holley that's been working fine up till tonight when it started flooding gas out the back vent tube any time the pedal is depressed.I've not had any problems till tonight,so this is what's bugging me.If needed it's a 454 with a 400 manual valve body.
Thanks to any and all who will help.

i had the same problem on the side of the road with my camaro it was dumping all the fuel out of the carb
i took an adjustable wrench and a screwdriver and adjusted the float adjuster on top of the bowl on the front and back
After playin with the adjustment i think i adjusted it out but im not sure
just play around with it and see what u get

I have numerous problems with the black phenolic floats that Holley installed in many of their newer carbs and now when ever I see one I toss it and get a brass one. They will sometimes absorb fuel and other times not, there does not seem to be any rhyme or reason why as other MFG's use them with no problem. Holley phenolic floats are junk, if you have them toss them you won't be sorry. Heavy floats will cause the symptoms you describe and so will a sticky needle, the viton tipped needles are the best and don't wear out like the steel ones do.
